The Grammy winner thanked those who alerted him of the oversight and posted a heartfelt apology.

“This lack of representation is something that is problematic and wide spread in our industry,” he wrote. “I regret not hiring and collaborating with women for this album–it’s ridiculous, it’s not who I am and it certainly doesn’t match how I’ve worked in the past. It doesn’t represent my current live show, which has a slew of diverse creators and collaborators, making this even more negligent on my part.”

Byrne’s last album, Love This Giant, was a joint project with St. Vincent (aka Annie Clark).
